Yamaha TX81z

Some pics of this Yamaha Tone Generator.

Though its only 4 operators , it sounds great.

Maybe a new classic??
It can be configured to act as 8 independent instruments.  .... each controlled on a different midi channel.

It's a 1-unit rackmount module ...basically a key-less version of the DX-11.
The sounds are similar to the DX-21 and DX-27. 

 The TX81Z has 5 banks of 32 voices. Banks A-D contain factory preset voices.
Use the PARAMETER keys to select banks I, A, B, C, D. Use the DATA ENTRY keys to select voices 1-32 in each bank.

 

...jUST 8 algorithms 

 A pull-out card lists the main operations of the TX81Z.

 --------------------------------------

You can edit your own voices... In single mode , press the edit-compare button.

 Use the PARAMETER keys to move through the parameters, Use the DATA ENTRY keys to change the datavalue. When the LCD shows several parameters at once, use the CURSOR keys to move the blinking cursor to the parameter you want to set.

..

While editing a voice, you can compare it with the original voice. Press EDIT/COMPARE. The LED will begin blinking, and the LCD will show a “c” in theupper left corner, indicating “Compare”.Use the PARAMETER keys to lookthrough the parameters. 

This editor looks good
